STENCIL-DUPLICATING APPARATUS.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed February 19, 1909. Serial No. 478,854.

T 0 all whom it may concern:

Be it known that I, ALBERT B. DICK, a citizen of the United States, residing at Lake Forest, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Stencil-Duplicating Apparatus, (Case A,) of which the following is a specification.

This invention relates particularly to that type of duplicating apparatus in which is employed a stencil-carrying drum or segment of a drum to which rotary or oscillatory movement is transmitted by suitable means and u )011 the surface of which is secured a stencif-sheet through which characters are imprinted upon an impression-sheet passing between the peri hery of such drum or segment and an un erlying pressure device, as, for instance, a roller.

The invention also relates particularly to means for applying to duplicating apparatus of this general class the ink which is assed through the interstices in the stcnci -sheet for the purpose of imprinting upon the im pression-shects.

Heretofore it has been the practice in both rotary and oscillatory duplicators to provide the drum with a foraminatcd metallic stencilcarrier, over which is stretched a pad of flannel or similar material, on the exterior of which the stencil is adjusted. The. ink has commonly been applied by means of a handbrush, and this, besides being attended by some diflicultyand inconvenience, particularly in machines wherein the entire surface of the drum has been covered by the forami nated stencil-carrier, has proved objectionable as lacking neatness, being wasteful of ink, and permitting the application of such ink to parts where it either could not be utilized or for which it was not intended.

Under the present invention, I make the inking apparatus of a duplicating machine practical y a part of that machine, either as to the container for theink alone, or as to the distributor for such ink alone, or as to both. In a preferred form of the invention, the drum is provided with an ink-container which may either be part of the permanent structure of the machine or adapted to receive ink in a can as put up at the factory. Suitable means are provided for permitting the flow of ink from such can or container to the interior of the drum, and a distributing device is employed, preferably manually operated, whereby the ink so deposited may be brushed or otherwise distributed over the interior of the drum either throughout the entire area thereof or at particular parts, as may be desired.

The invention is illustrated in the accompanying drawings, in which Figure 1. is'a side elevation of a stencilduplicating machine provided with my improvements; Fig. 2 is a central longitudinal section thereof; F ig. 3 is a transverse section, certain of the parts being shown in elevation; Fig. 4 is an end view of the ink-containing and -distributing apparatus; Fig. 5 is a transverse section, and Fig. 6 a longitudinal section, of a portion of the duplicator drum equipped with an ink-container of modified form Fig. 7 is an end view of ink-containing and -distributing apparatus constituting a modification of the corresponding apparatus shown in Fig. 4 Figs. 8, 10 and 11 are detail views hereinafter to be referred to and Fig. 9 is a transverse section, partly in elevation, of a simplified form of the apparatus, showing an ink-distributing apparatus, without, however, the ink-containing device or devices illustrated in the other figures.

Referring to these drawings, it will be seen that the stencil-carrying drum comprises the heads A, the foraminated stencil-carrier A and the ink-pad A over which is secured by any suitable means, as, for instance, the cross-bar A and clamp A, the stencil-sheet in which the characters have previously been formed. This drum is pivotally mounted in the upwardly-extcnding arms of the frame B, and coacting with the periphery thereof is a pressure-roller B mounted in hinged springpressed arms B with which coacts throw-off mechanism comprising shaft B, eccentrics B, and finger-piece B The drum is rotated by means of crank-handle C mounted upon a stub-shaft C journaled in the frame and transmitting motion to the pinions C and C Referring now more particularly to the inking apparatus, attention is first called to the simplified form in which this is illustrated in Fig. 9. Here, in addition to the shaft upon which the drum is mounted, there is a telescope-shaft a to one end of which is se cured the crank-handle a, the other end of said telescope-shaft (1-, within the drum, being provided with a sleeve (L to which is adjustably secured an ink-distributer a. In this form of apparatus, the ink is designed to be poured or otherwise deposited, from a suitable can or other container, into or upon the interior of the stencil-carrier, after which it is spread by means of the distributer a manually operated by means of the crankhandle a. It Will also be seen that the ink may be spread over the entire area of the stencil-carrier or over only such parts thereof as may be desired, this being entirely within the control of the operator. In the more com rehensive form in which the invention has een embodied, the ink is carried Within the drum, as above indicated and as illustrated in the other figures, which will now be described.

Referring more particularly to Fig. 3, it will be seen that the drum is mounted, at its rearward end, upon a hollow stub-shaft I; carried by one of the upwardly-extending arms of the frame. The other end of the drum is mounted upon a similar hollow stubshaft 6 carried, at b, by the other of the upwardly-extending arms ofthe frame. Keyed to a collar upon said stub-shaft is the pinion 0 provided on its inner face with a in (shown in dotted lines in Fig. 1) coacting with an orifice in the adjacent head of the drum, so that upon the application of power to said pinion through pmion C and crankarm C, rotary motion will be transmitted to the drum. The stub-shaft b is also provided with an enlarged head b for coaction with the brake c operated by the finger-piece B of the throw-off mechanism.

D designates the inking-rod. This extends through the hollow stub-shaft b its rearward end being received in the hollow stub-shaft b. This rod is operated by means of the crankhandle D extending at a right angle thereto and secured to the angular pieced forming one of two braking members, the other being the shoe dof the brake c. Said shoe is provided with a pin (1 which coacts with an onfice d in said angular piece. In Fig. 1, the parts are illustrated in the position which they occupy when the pressure-roller B 1s mo erative. Since it is under this condition t at a duplicator is commonly inked, the locking device just described is inoperative, i. e. the crank-handle D is free to be moved as hereinafter described. When, however, the finger-piece B of the throw-off mechanism is thrown to its alternative position, opposite to the position in which it is shown in Fig. 1, the brake-shoe under the influence of the spring (1 is thrown to inoperative position, and the coaction of the pm (1 with the orifice d locks the crank-handle D in the position in which it is illustrated in said figure.

Loosely mounted upon the inking-rod D, are two yokes D D, the ends of which are connected by guide-rods D, D Mounted so as to slide u on said guide-rods, is the inkcontaining an -distributing apparatus, two

forms of which are illustrated in the drawings. In the form illustrated chiefly in Figs. 2, 3 and 4, I employ an ink-container E mounted, as best shown in Fig. 2, upon the guide-rods D, D, and through which projects the inking-rod D. In the forward side e of the container is formed an oblique slot e Within which operates a lock for the inking-rod D. Said rod is provided, as best shown in Figs. 3, 8, 10 and 11, with a reduced portion F, and this portion is provided with a notch so formed that the cross-sectional outline through such reduced portion is substantially semicircular. The lock G, provided with the finger-piece g, is received ing with a coil-spring g in said slot (see Fig. 8) tending to press the lock upwardly. The slot e, and therefore the lock G, lie in the path of longitudinal movement of the inkingrod D, as best shown in Figs. 2 and 8. Said lock is provided, therefore, with a notch g of semicircular configuration. When the lock has been pressed inward against the tension of the coil-spring g, so that this notch coincides with the opening through the sideplate e and therefore through the ink-container, the end of the inking-rod D may be passed into said container until movement is arrested by the coactionof the edge of the reduced portion F with said lock G. Upon further depressing said look, so as to break this coaction, the end of the inking-rod may be passed entirely through the container and received within the hollow stub-shaft b, as shown in Fig. 3. This is the normal condition of the mechanism, and that which it oosnugly within the slot e, its lower end coactcupies when the pressure-roller is in operative position and the brake c in inoperative position, at which time the crank-handle lock (d (F) is operative to hold said crankhandle against accidental displacement.

The container E is provided with a fillingport E, which may be closed by a suitable screw-cap. The side-member e of said container is here shown as covered by a circular plate a secured in position by suitable screws. This is provided with a slot (2 open to the periphery of said plate e*, and in this slot operates the pin e carried by the lock G, the function of which will presently be explained. Secured to the face-plate 0 is a hub 6 having ears e", e Mounted upon said hub is a combined valve and latch H, preferably formed of spring-metal and operated by the finger-piece h. The member H may be readily secured in position upon the hub e by first causing the notches adjacent to the perforation therein to register with the ears cf, 6, then pressing said member rearw'ardly and turning it so that said notches and ears shall be out of engagement. Secured in any suitable manner to the inner face of the combined valve and latch, are stoppers h, if, the former, in the positioni lustrated in sea-sea" Fig. 2, covering the air-inlet port' communicating with'the interior of the container E, and-the latter, when in the position so illustrated, covering'theink outlet port in said container. The movement of the member-H to the left, Fig.- 2, simultaneously uncovers both of said ports, permitting ink in the con-- tainer-to escape therefrom and to fall onthe stench-carrier;- The latch function of the' member H isperformed by means ofa lightangled slot k with "WlllCh, aswell as with the slot e in the face-plate e the pin 0* of the lock G coacts. parts, in which-they are'illust-rated in Fig. '2, the lockG is in its innermost position, andthe-end: of the inking-rod distant from the crank ha-ndle thereon is housed in thehollow stub-shaft bf If, now, said'rod-be unlockedat- (1 (Z and moved outward from the drum (the ink-container-being held against similar movement), the reduced portion F of said rod-is brought into the path'of movementof the-lock; which is thereby moved upwardly by the spring'g but not sufficiently to per mitthe pin a to escape from the radial portion of the slot k At this-time, the reduced portion F is in contact with the semicircular notch g of said lock. If, now,-the rod D be given a partialrotation; so as to resent the semicircular notch therein to said ock G, the latter is permitted to rise to the position illus tratedin 10, thereby, first, lockingthe rod and the container together so that thelatter may be moved both longitudinally of the drum and circumferentially, and, second, permitting the pin e to rise sufficiently far in the slot-e as to allow the valve-member H to be" operated to uncover the air-inlet ort above and the ink-outletort below. I hen this' has been done, the lllklS permitted to drop, as above describedl The slot-andin device also precludes the release of the rod to restore itto inoperative osition while said ports are open, 't us guar ing against excessive flow of-inkfrom the container E.

Preferably secured to the ink-container or to some part movable therewith, is an inkdistributer, which may take any desired form. In the present instance, I have illustrated, fol-the 'urpose of this particular disclosure,- a brush attached to a plate i adju's'tably secured-to the rear face of the container E by screwsi-Ipng ecting through slots in said.- plate 'i. n.- ig.7,'- substantially the same arrangement -1s shown, the design being somewhat varied, however, and a spring 2' being employed to exert elastic pressure upon the brush. Said brusl1=may,-.1n-ei-ther construction, be adjusted, relatively to the-stencil-carrier, to-allo'w for wear, or may be lifted-entirely free-from the stencil-carrier and secured in such osition, if desired.

In Figs. 5 and '6, have illustrated a modificatio-n 'of the ink-containing device; the i In the normal position of the purpose here being to disclose the manner-in which, if desired, 'a permanent ink-container may be dispensed with; and, bymeans of a suitable cage-or holder, an*inkcan (as an original package) containing ink placed therein to perform practically the samefunction as the permanent container heretoforedescribed; Inithis modification, there-aresupported upon the guide rods D D both the ink-distributer (in substantially the form' heretofore described) and acageor can holder comprising a back-plate L' provided with ears adapted to receive bolts Z, 1. In the particular deviceillustrated, it is con templated that the cover of the-can-as-ap,- plied in the factory shall berem0ved'when it is desired to utilize the ink-and a cover substituted therefor made with special view -to" the-requirements of the duplicator, althtugh this isnot necessary in several forms inwhich the invention herein described may be employed- In theconstruction illustrated the specialcover is shown at M, this'havinganannularflange m corresponding to the flange of the usual ink-can cover, and a bear-- ing m for the 'inking-rod'corres ondingto the inking-rod D heretofore ex ained' In this case, the inking-rod is provi e'd at-its end with a notch adapted, when in its innermostposition, to coactwith the pin 'm in said bear-- ing. Said inking-rod is also provided with a 5 recess m with which coacts a spring-m in order that the-'can holder and can'carriedthereby may be; moved by the-inking-rod both longitudinally of the drum and circurn ferentially. The auxiliary cover M is also 1 provided with an "ink-outlet port m opened and closed bymeans of valve m. To secure the original package. can in position, after having substituted the auxiliary coverforthe regular cover thereof, it is only necessary 10 to place the bottom of suchcan against-the" late L and to secure it against displacement by means of the bolts l, l, which not only hold the can rigidly but also preclude the-possibility of di'sarrangement of-the auxiliary 1l cover M and consequent leakage of ink.

The operation of the apparatus has been explained to considerable-extent in connection with the description 'of the parts. Nor mally and when the inking apparatus is out of use, the parts occupy the position in= which they are illustrated in Figs. 1, 2 and 3. VVhenit is desired to apply ink to the stencil-carrier, either over its entire area or at certain portions thereof, the crank-handle D 20 is released from its lock (d (P), the container E held and the-rod drawnpart-iallyout-from the drum and then given a partial: rotation. As a result,-bymeans of the lock-'- ing device heretofore described, the end of the rod is rigidly attached to the ink-container, which; 1 together with the dlstrlbuter moving therewith, may now, by meansiof the" crank-handle, be moved to any desired point within the drum. The in k-outlet port is uncovered to permit the flow of sufficient ink, which is thus distributed over the stencilcarrier, and moreover, since the range of movement of the distributer is predetermined and limited to useful service of the carrier, the daubing of other parts with ink is precluded. After the ink-outlet port has been closed and sufficient ink has been distributed as above described, the lock G is pressed inward to its inoperative position, the rod similarly manipulated, and the crank-arm locked if desired. In the particular mechanism here shown and described, the throw-off mechanism (including handpiece B eccentric B and shaft 13) is so arranged as that when the machine is in operative position for duplicating purposes, the crank-handle will be locked. When said mechanism is so arranged as that (by reason of the depression of the pressure-roller) the machine is ino erative for duplicating purposes, the bralfe c is in operative position and the crank-handle released from the lock (1 (1 to permit the inking of the stencil-carrier as above. described.
